Fixed buffer overflow in password handling which could potentially be exploited by MySQL users with ALTER privilege on the mysql.user table to execute random code or to gain shell access with the UID of the mysqld process (thanks to Jedi/Sector One for spotting and reporting this bug).

mysqldump now correctly quotes all identifiers when communicating with the server. This assures that during the dump process, mysqldump will never send queries to the server that result in a syntax error. This problem is not related to the mysqldump program's output, which was not changed. (Bug#1148)

Fixed table/column grant handling - proper sort order (from most specific to less specific, see Section 5.5.6, « Contrôle d'accès, étape 2 : Vérification de la requête ») was not honored. (Bug#928)

Fixed overflow bug in MyISAM and ISAM when a row is updated in a table with a large number of columns and at least one BLOB/TEXT column.

Fixed MySQL so that field length (in C API) for the second column in SHOW CREATE TABLE is always larger than the data length. The only known application that was affected by the old behavior was Borland dbExpress, which truncated the output from the command. (Bug#1064)

Fixed ISAM bug in MAX() optimization.

Fixed Unknown error when doing ORDER BY on reference table which was used with NULL value on NOT NULL column. (Bug#479)
